edges and 21% of said bricks 15 and 16 are i inclined to conform to the inclination of said flanges 11 and 12 so as to form a dove-tail connection therewith. rlhe iianges 16 and 17 of the brick are adapted to cover the edges 2l and 25 of the flanges 10 and 11 and 12 after said bricks are'slid into position between said latter flanges. A locking member l26 is adapted toseal, between the ianges 18 and the frame 8 and Vbe held in position seat-- ed on -the upper edge of said brick by means of tapering pins adapted to project through openings :28 in said frame 8 and l into tapering openings 29 in said member 26.

The pins 27 are provided with openings 30 which are adapted to project partly outwardly oi' the trame 8 so that by means of a wedge member lsaid pins may be removed at will in order tol release the member 26. lt will be seenv that the `tire bricks and 16 will be so mounted in their bearings that their inner edges will be suitably separated and that an opening 32 is provided in the member 26 which alines with the se1ni-cylini (l1-ical grooves 20 and 211 through which member 33 may be projected into the cylindrical opening 34 formed by said grooves 20 and 21, the member 33 being cylindrical and of a greater diameter than the bore or opening-34, and tapering' at its lower end 35 it is adapted to force the bricks 15 and 16 apart causing them to be wedged in the door frame 8 so that theycannot be removed without first removing-the member 33, and then the member 26.

Seated between the frame 8 and the brick 15 and 16 are bars 36, 37 and 38 each having otlsets 39 whereby air spaces elO-are formed between the frame 8 and the fire brick so as to keep as much heat as possible from the frame 8. If desired, for the purpose of et'- fectively holding the parts of the swinging doors in position the tie bolts 35" may be used, adapted to clamp the lire-bricks closely against the frame-work of the door.

The hinge members il and L12 are offset trom the frame 2 and doors 4, 5, 6 and lier the purpose vof allowing said doors to open wide. v

W hen the bricks in one of the doors have become burned out they can readily and quickly he renewed by removing the plate 26 and then sliding into position another pair of bricks'as illustrated in Fig. 5. By means of my invention the iiames and heat in the oven are kept outof direct contact with indefinitely Having now described i115' invention, tha 5 wif/ch claim to he new :inc iicsii'e to pio- .rrure by Letters Patent A l. ,A coke oven domi' ccnisting of i imm@ ha iiangcs on iis hct'mni and fwd vertlczii siiics, i1 piiii` of fine hiicks adapted tc l0 scat be-wccn said ihn-ges :1 ifcincvuhic cmci for said bricks, Said hiickg having firing; i. adapted to coxi 'hc cdgcs ci Said anges :and ih@ cdga of said cm'cxf. :iceis for hoiding saici bricks from contact with i5 :mid frame., and a wedge naptcci to .forcesziid hi'ickis apart whereby they are bound in position in Said fiume.
